GRWA2024 Automechanika Shanghai Exhibition ——Muffler Series Product Introduction

    Muffler is one of the products we will focus on exhibiting at the 2024 Automechanika Shanghai Exhibition, including box-type muffler, pipe-type muffler and diesel internal combustion engine muffler. Below we will give you a comprehensive introduction to these products.

1. Box-Type Muffler

    The unique dual-output system design can transform a single exhaust system into a dual-output system without losing any performance. Made of high-quality stainless steel, each joint is precisely calculated and fully welded, and the sealing and stability are more guaranteed; compared with the traditional T-shaped or Y-shaped straight pipe design, the box-type muffler shows a better response speed and exhaust efficiency.

    Perforated pipe technology: The oblique perforated pipe design effectively disperses the airflow, reduces back pressure, and improves the layering and clarity of the exhaust sound.

    Internal structure: integrated perforated pipe, spiral pipe, baffle, S drum, multiple noise reduction and airflow optimization, to ensure smooth exhaust and proper noise control.

2. Tube-Type Muffler

    The tube-type muffler can increase horsepower, improve the appearance and style of the vehicle, and make the sound smoother, deeper and more textured. According to the material, it can be divided into SS201, SS304 and SS409; among them, SS304 has the best performance and is suitable for high-end vehicle modification. Surface treatment methods include polishing, brushing, titanium plating (using vacuum ion plating technology, the surface is not easy to fade, more beautiful and durable) and painting, which gives the product more durable performance and a unique appearance.

3. Diesel Internal Combustion Engine Muffler

    Diesel internal combustion engine muffler is mainly used for silencing large diesel trucks and other heavy equipment. Its shell is significantly longer than that of automobile and light truck mufflers, and its length-to-diameter ratio is also significantly greater than that of automobile and light truck mufflers. Mufflers for large-displacement internal combustion diesel engines installed on large highway trucks and large stationary engines. It can reduce back pressure, thereby providing better performance and increasing mileage while reducing noise levels.

    The surface is treated with black spray paint, the shell is thickened, and advanced two-protection welding technology is used for welding, which has good crack resistance and is firm and reliable.

4. Comprehensive Comparison:

（1）Internal structure:

    1. Box-type muffler: The interior usually contains multiple soundproof chambers and reflective panels, as well as some sound-absorbing materials. These structures help to reflect, refract and absorb sound waves, thereby reducing noise.

    2. Tube-type muffler: The internal structure is relatively complex, including perforated tubes, expansion chambers. These structures achieve noise reduction through the reflection and refraction of sound waves in the tube and the energy dissipation in the expansion chamber.

    3. Diesel internal combustion engine muffler: The interior usually includes multiple cascaded muffler chambers, perforated plates, sound insulation materials and reflective panels. These structures are specially designed to handle the high-temperature exhaust gas and rough exhaust flow of diesel engines while achieving noise reduction.

（2）Appearance design:

    1. Box-type muffler: Features a unique dual output system and oblique perforated pipes, and the design focuses more on improving the appearance and style of the vehicle.

    2. Tube-type muffler: Features a straight perforated pipe and a variety of material selection appearance design. It is relatively compact and can be closely integrated with the exhaust system to maintain the overall beauty of the vehicle.

    3. Diesel internal combustion engine muffler: The appearance design is relatively simple, focusing more on durability and noise reduction. It is usually larger in size and requires more installation space.

（3）Functional positioning:

    1. Box type muffler: mainly used for passenger cars and light commercial vehicles to reduce noise and improve vehicle performance.

    2. Tube type muffler: also suitable for passenger cars and light commercial vehicles, more focused on horsepower and vehicle performance improvement.

    3. Diesel internal combustion engine muffler: mainly used for large diesel trucks and other heavy equipment, focusing on reliability and durability under high temperature and heavy load conditions.

5. Overall Advantages

    High-quality materials: 4 stainless steel materials with high nickel content are used, combined with 316L welding rods to ensure product durability and reliability.

Exquisite craftsmanship: Class A polishing and unique tooling positioning welding process, the internal structure is welded three times, the weld is firm, and the service life is effectively extended.

    Comprehensive performance: GRWA muffler series products are all made of high-quality muffler materials (steel mesh, heat-insulating non-woven fabric, muffler cotton), and the well-designed internal structure achieves efficient noise reduction and airflow optimization, bringing drivers a more comfortable and safe driving experience.

    At the 2024 Automechanika Shanghai Exhibition, we sincerely invite you to visit the exhibition and experience the extraordinary driving experience brought by the GRWA muffler.
